Hi,
Apologies for the newbie assumptions and questions that follow...
I am thinking of using Sequoia in an environment where the hosting
machines will be restarted every day. Each installation would comprise 4
Windows XP Embedded boxes, each running a Sequoia controller and a Derby
backend. Reads would be performed on the local backend while writes
would be replicated across the backends. Each box will restart overnight
and at present these is no mechanism for coordinating restarts.
So my questions are:
1. If I attempt to cleanly shut down the cluster, I presume I am likely
to hit the 'last man standing' restart order problem as I cannot easily
control the shutdown order
2. Would it be easier to stagger shutdown so that at least one cluster
member is active at all times, effectively keeping the cluster up?
3. If I go for 2, what happens if there is a catastrophic failure (eg
power out) - presumably I would need to detect this and restart the
controllers with force/init?
4. There will be minimal writes happening at the time of shutdown, so
can I avoid all of the restart synchronisation by restarting with
force/init?
Thanks in advance,
John.
